(SCHOOL POND AREA)
(1) WATER IS ONE OF THE
(1) EARTH & WATER VITAL FACTORS TO
(GRAPHICS); BODY WATER SUSTAIN LIFE ON EARTH.
COMPOSITION SURPRISINGLY, THE
ADULT HUMAN BODY IS
2/3 OR 60% WATER
WHICH IS SIMILAR TO
OUR PLANET, WHILE
BABIES ARE 78%.
(2) CELLULAR FUNCTIONS
WITH FLUID (2) ALTHOUGH WATER
SUSTAINS LIFE, IN MOST
UNEXPECTED
INSTANCES, WATER MAY
ALSO BE A CAUSE OF
DEATH.
 (3) FRIEND / FOE GRAPHICS (3) IS WATER A FRIEND OR
FOE?

ON CAM 2: STUDENT B (HEALTH

CENTER – AMPAYON)

(1) PICTURES / GRAPHICS (1) WATER MAINTAINS THE

OF: VIRUS; BACTERIA; BODILY FUNCTIONS OF
PROTOZOA; A HUMAN BEING.
PARASITES HOEVER, THEY MAY
ALSO BE A VEHICLE
FOR DISEASE-CAUSING
MICROORGANISMS,
TERMED AS
PATHOGENS. WHEN
THESE PATHOGENS
ARE INGESTED BY THE
BODY THROUGH THE
MOUTH, THEY CAUSE
WATER-BORNE
DISEASES.

(2) ONE DISEASE HUMANS

CAN GET FROM
CONTAMINATED WATER
IS DIARRHEA. IT IS A
COMMON SYMPTOM OF
INTESTINAL INFECTION
CAUSED BY THESE
PATHOGENS LIKE VIRUS,
BACTERIA, PROTOZOANS,
PARASITES, ETC.
(2) MAP OF SOWATO,
SOUTH AFRICA WITH (3) A STUDY ON DIARRHEAL
LOCATION ICON DISEASES IN SOWETO,
SOUTH AFRICA LAST
2020 SHOWED THAT
CHILDREN LESS THAN 5
YEARS OLD WERE
GREATLY AFFECTED AS
 OBSERVED TO BE
ADMITTED AMONG
HEALTHCARE FACILITIES
COMPARED TO ADULTS.

(3) POP – UP:

WHAT ARE THE COMMON (3) IN THE PHILIPPINE
WATER-BORNE DISEASES IN CONTEXT, WHAT IS THE
THE PHILIPPINES? COMMON WATER-BORNE
DISEASES?

DATA GRAPHICS FEVER, CHOLERA, ACUTE
BLOODY DIARRHEA,
ACUTE VIRAL HEPATITIS
(HEPATITIS A), AND
ROTAVIRUS. ALTHOUGH
THE INFECTION WAS
DECLINING FOR 2021 –
2022 YET THE DEATHS
TALLIED LAST 2021 AND
2022 WERE BOTH 7 WITH
A TOTAL OF 14 DEATH
CASES.
ON CAM 3: STUDENT C (AM NHS
– WASHING AREA – SCI LAB)

(1) PICTURES / GRAPHICS (1) ONE MAJOR CAUSE OF

OF: WATER DIARRHEA IS WATER-
CONTAMINATION WITH CONTAMINATION WITH
MICROORGANISMS THE PRESENCE OF
WATER-BORNE DISEASE
MICROORGANISMS.

(2) DOST LOGO & BCWD (2) ALL SOURCES OF WATER

LOGO / PICTURE OF SUPPLY CAN BE
BCWD WATER CONTAMINATED, IF
LABORATORY. MEASURES ARE NOT
TAKEN TO FILTER & BE
EXAMINED BY
APPROPRIATE WATER
LABORATORIES AS SAFE
TO DRINK.

(3) UPON LOOKING IN A

MICROSCOPE, ONE
COULD FIND A COLONY
OF VARIED
MICROORGANISMS
INCLUDING INVISIBLE
PARASITES THAT THRIVE
ON WATER.

(4) A BACTERIA CALLED

Salmonella typhi CAUSES
TYPHOID FEVER WHICH
ACCOUNTS ALMOST 200
MILLION PEOPLE
WORLDWIDE SUFFER
FROM THIS ILLNESS. THIS
EMERGED DUE TO POOR
SANITATION AND
DRINKING OF UNSAFE
WATER, MAY ALSO
 SPREAD THROUGH
CONTAMINATED FOOD.
THE DISEASE IS
CONSIDERED HIGHLY
CONTAGIOUS,
AFFECTING NOT ONLY AN
INDIVIDUAL BUT A WHOLE
COMMUNITY.

(5) SALMONELLA TYPHI IS AN

AEROBIC
MICROORGANISM,
GROWING BEST IN AN
ENVIRONMENT WITH THE
PRESENCE OF OXYGEN
AND MAY ALSO SURVIVE
WITH LOW OXYGEN
LEVEL. THEY ARE ROD-
SHAPED WITH A SIZE OF 1
- 3 MICROMETER IN
LENGTH BY 0.5 - 0.6
MICROMETER IN
DIAMETER. MAY COME IN
PAIRS OR SINGLY,
REPRODUCING BEST IN
TEMPERATURE OF 37
DEGREES CELSIUS.
THEY’RE MOBILE DUE TO
THEIR FLAGELLATED OR
TAILED STRUCTURE.

(6) ABOUT 9 DEATHS WERE

RECORDED IN CARAGA
BY THE PHILIPPINE
STATISTICS AUTHORITY
(PSA) LAST 2019 DUE TO
TYPHOID FEVER.
ON CAM 4: STUDENT B & C
(HEALTH CENTER)

(1) ANOTHER LIFE-

THREATENING DISEASE-
CAUSING
MICROORGANISM IS
Vibrio cholerae WHICH IS
THE CAUSE OF THE
DISEASE “CHOLERA”. IT
INFECTS THE INTESTINE
CAUSING SEVERE
DEHYDRATION &
DIARRHEA AND MAY KILL
A PERSON WITHIN DAYS
OR HOURS IF LEFT
UNTREATED.
MARGINALIZED
COMMUNITIES WHERE
POOR SANITATION AND
WATER CONTAMINATION
IS RAMPANT ARE
FACTORS FOR THE
ORGANISM TO THRIVE.

(2) VIBRIO CHOLERAE IS A

COMMA – SHAPED
BACTERIUM, LIVING IN AN
ANAEROBIC
ENVIRONMENT OR
WITHOUT OXYGEN.
SIMILAR TO SALMONELLA
TYPHI IT HAS A TAIL
STRUCTURE. THE SIZE OF
THE BACTERIUM VARIES
RANGING FROM 1-3
MICROMETER IN LENGTH
BY 0.5 – 0.8 MICROMETER
IN DIAMETER.
(3) THE PSA REPORTED NO
DEATHS OF CHOLERA IN
CARAGA LAST 2019 BUT
HAS TALLIED 1 DEATH
LAST 2018.

(4) ANOTHER TYPE OF

BACTERIA CAUSES A
SYMPTOM OF ACUTE
BLOODY DIARRHEA, THE
ILLNESS SUGGESTS AN
INFECTION CAUSED BY
CAMPYLOBACTER,
SAMONELLA, SHIGELLA,
OR SHIGA-TOXIN
ESCHERICHIA COLI. IT IS
OFTEN CAUSED BY
SHIGELLA, THE DISEASE
IS ALSO KNOWN AS
SHIGELLOSIS WHEN
CAUSED BY Shigella
dysenteriae. THE DISEASE
CAN BE SPREAD
THROUGH
CONTAMINATED WATER
AND FOOD.

(5) SHIGELLA IS A ROD

SHAPED, NON-SPORE
FORMING, AND NON-
MOTILE OR NON-MOVING
BACTERIA SINCE IT HAS
NO FLAGELLA OR TAIL
TO MAKE IT MOVE
FREELY. THEIR SIZE
VARY FROM 1 – 3
MICROMETER LONG BY
0.4 – 0.6 MICROMETER IN
DIAMETER.
(6) ITS OTHER TERM IS
DYSENTERY. DUE TO ITS
BLOODY PRESENCE IN
THE STOOL IT IS
CONSIDERED AN URGENT
MEDICAL EMERGENCY.

(7) THERE ARE 108 DEATH

CASES OF DYSENTERY IN
CARAGAR REGION LAST
2019 AS PER REPORT OF
PSA.
ON CAM: STUDENT A (1) ASIDE FROM BACTERIA,
(AMPAYON FOOD MARKET) VIRUSES CAN ALSO
CAUSE SEVERE
DEHYDRATION DUE TO
DIARRHEA. HEPATITIS A
WHICH IS CONSIDERED
HIGHLY CONTAGIOUS
ESPECIALLY AREAS
WITHOUT OR DISPLAYS
POOR SANITARY
PRACTICES & LACKS
CONTAMINATED FOOD
AND WATER SUPPLY.

(2) HEPATITIS A VIRUS IS AN

ENTERIC KIND OF VIRUS,
HENCE, AFFECTING THE
INTESTINES. IT IS A
SINGLE STRAND RNA
(RIBONUCLEIC ACID)
MOLECULE ENCLOSED IN
A CAPSID (PROTEIN
SHELL OF A VIRUS). ITS
SIZE RANGES FROM 27 –
32 NANOMETER MUCH
MINUTE OR VERY SMALL
COMPARED TO A
BACTERIA.

(3) ABOUT 56 DEATH CASES

WERE NOTED BY PSA IN
CARAGA REGION LAST
2019 DUE TO THE VIRAL
INFECTION.

(4) ALTHOUGH HEPATITIS A

IS CONTAGIOUS, YET,
MOST PEOPLE
DEVELOPED A LIFELONG
IMMUNITY AFTER
CONTRACTING HEPATITIS
ON CAM: STUDENT A
(AMPAYON FOOD MARKET)
(1) ROTAVIRUS IS A
CONTAGIOUS DISEASE IN
A STABLE ENVIRONMENT,
WHICH CAN BE
TRANSMITTED THROUGH
CONTAMINATED FOOD
OR WATER AND DIRECT
CONTACT OF SURFACES
OR OBJECTS.

(2) THE VIRION OF

ROTAVIRUS IS A TRIPLE-
LAYERED PARTICLE WITH
AN EMBEDDED SPIKE
ATTACHMENTS IN ITS
OUTER LAYER.

(3) UNLIKE HEPATITIS A

VIRUS, ROTAVIRUS IS A
DOUBLE STRANDED RNA
SEGMENTS. THE SPIKE
ATTACHMENTS IN ITS
OUTER LAYER SERVE AS
A MEDIATOR THAT
 CONNECTS THE VIRUS
INTO ITS HOST CELLS
FOR EASIER
INFILTRATION INSIDE THE
CELL.

(4) SEVERE WATERY

DIARRHEA IS ONE OF THE
SYMPTOMS OF THIS
DISEASE.

(5) FROM 2015 – 2019 THERE

WERE NO DEATH CASES
IN CARAGA REGION BUT
THERE 257 WHO WERE
DIAGNOSED WITH
ROTAVIRUS AS PER PSA
REPORT LAST 2019.

ON CAM 6: STUDENT A
(WASHING AREA & SCHOOL
TOILET FACILITY)
(1) WITH ALL THESE
SITUATIONS THAT LEAD
TO HUMAN HEALTH
CHALLENGES, WE ARE
LEFT WITH THIS
THOUGHT TO PONDER
ON? IS WATER REALLY A
FRIEND OR FOE?

(2) WATER IS AN ESSENTIAL

MATTER TO
CONTINUOUSLY
SUPPORT THE FLOW OF
LIFE ON EARTH. BUT ITS
FINITE SUBSTANCE CAN
SOMETIMES BE SPOILED
AND MAY TURN AGAINST
 US WHEN NEGLECTED
AND EXPLOITED.

(3) THE PRESENCE OF

PATHOGENS IN WATER IS
A MIRROR OF HOW
HUMANS MANAGE THE
USE OF WATER MOST
ESPECIALLY HOW WE
INFLUENCE AND HOLD
ACCOUNTABLE OF ITS
UTILIZATION AS AN
IMPORTANT FACTOR FOR
THE SURVIVAL OF OUR
CIVILIZATION.

(4) WATER IS POWER, IT IS

HOW THE USER
MANIPULATE THAT
POWER INTO GOOD USE.

(5) I THINK THE QUESTION IS

ARE WE A FRIEND OR
FOE TO WATER?
